BACKGROUND

1. Technical Field

The disclosure relates to an air conditioning compressor for vehicles, and more particularly to an air conditioning compressor driven by electrical power.

2. Related Art

Refer to FIG. 1 and FIG. 2 for the air conditioning compressor for vehicles of the prior art. The air conditioning compressor comprises a compressor A, an electromagnet B, a belt pulley C, and a clutch disk D. A shaft A1 extends from the compressor A. The electromagnet B is configured at the exterior of the compressor A and surrounds the shaft A1. The belt pulley C is configured at the exterior of the electromagnet B. The belt pulley C joints with the electromagnet B using the shaft such that the belt pulley C may rotate at the exterior of the electromagnet B. The clutch disk D is arranged at the outer surface of the belt pulley C. The clutch disk D comprises a sleeve D1. The sleeve D1 passes through the belt pulley C and the electromagnet B and then joints with the shaft A1 of the compressor A. When the air conditioning compressor for vehicles of the prior art operates, an external driving device E, for example vehicle engine, is used as the main power source. The driving device E is configured with a rotating wheel E1 encircled with a belt F. The belt F then encircles the belt pulley C. Thus, when the air conditioning compressor for vehicles of the prior art operates, for example the air conditioner in the vehicle turns on, the electromagnet B is applied with electrical power such that the electromagnet B generates non-directional magnetism. The electromagnet B absorbs the clutch disk D such that the clutch disk D and the belt pulley C are tightly absorbed. The sleeve D1 of the clutch disk D connects to the shaft A1 of the compressor A. In the driving device E, the belt F drives the belt pulley C to rotate, and then the belt pulley C drives the clutch disk D to rotate. Then the clutch disk D drives the shaft A1 of the compressor A to rotate such that the air conditioning compressor for vehicles of the prior art may operate accordingly.

However, the driving device E is employed as a power source to drive the conditioning compressor of the prior art. Rising gas prices, energy-saving and carbon reduction has drawn people's attention. In particular, carbon dioxide emissions increase when a vehicle stops traveling and the air conditioner continues operating, and gradually result in severe global warming effect.

The detailed characteristics and advantages of the disclosure are described in the following embodiments in details, the techniques of the disclosure can be easily understood and embodied by a person of average skill in the art, and the related objects and advantages of the disclosure can be easily understood by a person of average skill in the art by referring to the contents, the claims and the accompanying drawings disclosed in the specifications.

Refer to FIG. 3 and FIG. 4 illustrating an air conditioning compressor for vehicles. It is not required to change the internal structure of the air conditioning compressor for vehicles of the prior art such that the conditioning compressor may be driven by the electrical power. The air conditioning compressor for vehicles of the disclosure comprises a compressor 1 and a driving device 2.

The compressor 1 comprises a shaft 11, which extends from the compressor 1 to the exterior of the compressor 1. In one embodiment, the compressor 1 may be a plate reciprocating compressor, a piston reciprocating compressor, or a vane compressor.

The driving device 2 is driven by the electrical power and configured at the exterior of the compressor 1. In one embodiment, the driving device 2 may be an external rotor motor comprising a stator 21 and a rotor 22.

The stator 21 is configured to have a shaft hole 211. The shaft 11 of the compressor 1 passes through the shaft hole 211 such that the stator 21 is configured at the exterior of the compressor 1. At least two electrical power transmission lines 212 having different polarities are configured in the stator 21. The two electrical power transmission lines 212 connect to an external power source, such as vehicle batteries or other power sources. The stator 21 comprises at least one core encircled by a winding. The electrical power transmission lines 212 having at least two polarities extend from the winding, and then connect to the external power source. The power source (such as direct current power source) passes though the winding such that the stator 21 may generate directional (forward or reverse) rotating magnetic torque.

The rotor 22 is configured at the exterior of the stator 21. One side of the rotator 22 is recessed to form a receiving slot 221. The receiving slot 221 is used to accommodate the stator 11. A plurality of magnetic elements 222 are configured on the internal wall of the receiving slot 221. A sleeve portion 223 is further formed in the receiving slot 221 of the rotor 22. The plurality of magnetic elements 222 of the rotor 22 are spaced at intervals to correspond to the outer surface of the stator 21. The sleeve portion 223 of the rotor 22 may pass through the shaft hole 211 of the stator 21 to connect to the shaft 11 of the compressor 1.

When air conditioning compressor for vehicles operates, for example, the air conditioner of the vehicle turns on, the stator 21 of the driving device 2 may generate directional (forward or reverse) rotating magnetic torque after the electrical power is applied to the driving device 2. A torque is inducted by way of electromagnetic induction through the stator 21 of the driving device 2 to enable the rotor 22 to rotate. The rotor 22 then drives the shaft 11 of the compressor 1 such that the compressor 1 may be driven to operate by way of applying the electrical power. The conventional air conditioning compressor for vehicles not only consumes more gas of the vehicles, but also makes the global warming effect much more severe due to the carbon dioxide emissions from the vehicle engines. Thus, the problem that the air conditioning compressor for vehicles uses the vehicle engine as the main power source may be avoided by the embodiment of the disclosure.

Refer to FIG. 5, FIG. 6 and FIG. 7 illustrating another embodiment of an air conditioning compressor for vehicles of the disclosure. The air conditioning compressor for vehicles comprises a compressor 1 and a driving device 3. The driving device 3 is driven by electrical power and is configured at the exterior of the compressor 1. The driving device 3 may be an inner-rotor type motor, which comprises a stator 31 and a rotator 32.

The stator 31 is configured to have a shaft hole 311. The shaft 11 of the compressor 1 passes through the shaft hole 311 such that the stator 31 is configured at the exterior of the compressor 1. At least two electrical power transmission lines 312 having different polarities are configured in the stator 31. The two electrical power transmission lines 312 connect to an external power source, such as vehicle batteries or other power sources. The stator 31 comprises at least one core encircled by a winding. The electrical power transmission lines 312 having at least two polarities extend from the winding, and then connect to the external power source. The power source (such as direct current power source) passes though the winding such that the stator 31 may generate directional (forward or reverse) rotating magnetic torque.

The rotor 32 is a magnetic element. The rotor 32 is configured at the shaft 11 of the compressor 1, and is correspondingly configured in the shaft hole 311 of the stator 31. The rotor 32 and the shaft hole 311 of the stator 31 are spaces at intervals and correspond to each other.

When air conditioning compressor for vehicles operates, for example, the air conditioner of the vehicle turns on, the stator 31 of the driving device 3 may generate directional (forward or reverse) rotating magnetic torque after the electrical power is applied to the driving device 3. A torque is inducted by way of electromagnetic induction through the stator 31 of the driving device 3 to enable the rotor 32 to rotate. The rotor 32 then drives the shaft 11 of the compressor 1 such that the compressor 1 may be driven to operate by way of applying the electrical power.

In another embodiment, the external power source may be the battery configured in the vehicle or an auxiliary battery. The power transmission lines 212 and 312 of the driving device 2 and 3 mat connect to the battery in the vehicle to obtain electrical power. In another embodiment, the auxiliary battery may be configured in the vehicle such that the power transmission lines 212 and 312 of the driving device 2 and 3 mat connect to the auxiliary battery to obtain electrical power.

In summary, the technical features of the disclosure lies on configuring the driving device 2 and 3 driven by the electrical power at the exterior of the compressor 1. Thus the electrical power may be the main power source of the compressor 1 such that the compressor 1 may be driven by the electrical power. The conventional air conditioning compressor for vehicles not only consumes more gas of the vehicles, but also makes the global warming effect much more severe due to the carbon dioxide emissions from the vehicle engines. Thus, the problem that the air conditioning compressor for vehicles uses the vehicle engine as the main power source may be avoided by the embodiment of the disclosure.
